Description OSIDB Bzimport 2024-09-18 08:21:50 UTC 
In the Linux kernel, the following vulnerability has been resolved:

hwmon: (w83627ehf) Fix underflows seen when writing limit attributes

DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large
negative number such as -9223372036854775808 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.
